Andrea Corn has been married to her second husband for 23 years. They dated for five years before that and have five children between them.
For her, even with a husband who is 12 years older and different backgrounds, it works.
As a Florida psychologist, she often tells patients, "Words are like weapons -- they can sting, pierce and penetrate the skin and the wounds can take a long time to heal."
As for enduring love, Corn said couples ultimately need to "develop empathy ... to put oneself in the other person's shoes, and learn to refrain from saying everything and not causing unnecessary pain and hurt feelings."
